Mismatch Repair

6.4K
Organisms are capable of detecting and fixing nucleotide mismatches that occur during DNA replication. This sophisticated process requires identifying the new strand and replacing the erroneous bases with correct nucleotides. Mismatch repair is coordinated by many proteins in both prokaryotes and eukaryotes.

Overview of DNA Repair

33.5K
In order to be passed through generations, genomic DNA must be undamaged and error-free. However, every day, DNA in a cell undergoes several thousand to a million damaging events by natural causes and external factors. Ionizing radiation such as UV rays, free radicals produced during cellular respiration, and hydrolytic damage from metabolic reactions can alter the structure of DNA. Damages caused include single-base alteration, base dimerization, chain breaks, and cross-linkage.

Base Excision Repair

26.2K
One of the common DNA damages is the chemical alteration of single bases by alkylation, oxidation, or deamination. The altered bases cause mispairing and strand breakage during replication. This type of damage causes minimal change to the DNA double helix structure and can be repaired by the base excision repair (BER) pathways. BER corrects damaged DNA sequences by removing the damaged base and restoring the original base sequence using the complementary strand as a template.

DNA Distortion and Damage
Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...

Summary
This summary is machine-generated.

Aortic valve repair is generally not recommended for most incompetent bicuspid aortic valves. Valve replacement offers better long-term outcomes for patients with malformed or calcified valves.

Area of Science:

  • Cardiovascular Surgery
  • Cardiac Valve Disease

Background:

  • Bicuspid aortic valve (BAV) is a common congenital heart defect.
  • Incompetent BAV can lead to aortic regurgitation and heart failure.
  • Surgical management of incompetent BAV remains a challenge, particularly in young patients.

Purpose of the Study:

  • To evaluate the efficacy of aortic valve repair versus replacement in patients with incompetent bicuspid aortic valve.
  • To define criteria for successful aortic valve repair in the context of BAV.

Main Methods:

  • Review of surgical outcomes for patients with incompetent bicuspid aortic valve undergoing repair or replacement.
  • Analysis of patient selection criteria for aortic valve repair.
  • Comparison of long-term results between repair and replacement strategies.

Main Results:

  • Aortic valve repair is suitable only for select cases with normal or minimally abnormal cusp tissue and specific anatomical configurations.
  • Most patients with incompetent BAV present with malformed, fibrotic, or calcified cusps, making repair less favorable.
  • Valve replacement (pulmonary autograft, mechanical, or bioprosthetic) is often associated with better long-term outcomes than repair for these patients.

Conclusions:

  • Surgical repair of incompetent bicuspid aortic valve is limited to a small subset of patients with specific cusp characteristics.
  • For the majority of patients with incompetent BAV, particularly those with degenerative valve changes, valve replacement provides superior long-term results.
  • Careful patient selection and consideration of valve pathology are crucial in determining the optimal surgical strategy for incompetent BAV.
